Semisynthetic analogs of Rapamycin (Macrolldes) being immunomodul ators
10 This is a continuation-in-part of U.S. patent application Serial No.
155,064, filed November 19, 1993.
Technical Field
The present invention relates to novel chemical compounds having
15 immunomodulatory activity and synthetic intermediates useful for the
preparation of the novel compounds, and in particular to macrolide
immunomodulators. More particularly, the invention relates to semisynthetic
analogs of rapamycin, means for their preparation, pharmaceutical compositions
containing such compounds and methods of treatment employing the same.
20
Background of the Invention
The compound cyclosporine (cyclosporin A) has found wide use since its
introduction in the fields of organ transplantation and immunomodulation, and
has brought about a significant increase in the success rate for transplantation
25 procedures. Recently, several classes of macrocyclic compounds having potent
immunomodulatory activity have been discovered. Okuhara et ai., in European
Patent Application No. 184,162, published June 11, 1986, disclose a number of
macrocyclic compounds isolated from the genus Streptomyces.
Immunosuppressant FK-506, isolated from a strain of S. tsukubaensis, is a
30 23-membered macrocyclic lactone represented by the formula shown below.
WO 95/14023
PCT/US94/12777
FK-506
5 Other related natural products, such as FR-900520 and FR-900523, which differ
from FK-506 in their alkyl substituent at C-21, have been isolated from S.
hygroscopicus yakushimnaensis. Yet another analog, FR-900525, produced by
S. tsukubaensis, differs from FK-506 in the replacement of a pipecolic acid
moiety with a proline group. Unsatisfactory side-effects associated with
10 cyclosporine and FK-506 such as nephrotoxicity, have led to a continued search
for immunosuppressant compounds having improved efficacy and safety.
Rapamycin is a macrocyclic triene antibiotic produced by Streptomyces
hygroscopicus, which was found to have antifungal activity, particularly against
Candida albicans, both in vitro and in vivo (C. Vezina et al., J. Antibiot. 1975,
15 28, 721; S. N. Sehgal et al., J. Antibiot. 1975, 28, 121; H. A. Baker et al., J.
Antibiot. 1978,57, 539; U.S. Patent No. 3,929,992; and U.S. Patent No.
3,993,749).
WO 95/14023
PCT/US94/12777

Rapamycin
Rapamycin alone (U.S. Patent No. 4,885,171) or in combination with
5 picibanil (U.S. Patent No. 4,401,653) has been shown to have antitumor activity.
In 1977, rapamycin was also shown to be effective as an immunosuppressant in
the experimental allergic encephalomyelitis model, a model for multiple
sclerosis; in the adjuvant arthritis model, a model for rheumatoid arthritis; and
was shown to effectively inhibit the formation of IgE-like antibodies (R. Martel
10 et al., Can. J. Physiol. Pharmacol., 1977, 55, 48).
The immunosuppressive effects of rapamycin have also been disclosed in
FASEB, 1989, 3, 341 1 as has its ability to prolong survival time of organ grafts
in histoincompatible rodents (R. Morris, Med. Sci. Res., 1989, 77, 877). The
ability of rapamycin to inhibit T-cell activation was disclosed by M. Strauch
15 (FASEB, 1989, 3, 341 1). These and other biological effects of rapamycin are
reviewed in Transplantation Reviews, 1992, 6, 39-87.
Mono-ester and di-ester derivatives of rapamycin (esterification at
positions 31 and 42) have been shown to be useful as antifungal agents (U.S.
Patent No. 4,316,885) and as water soluble prodrugs of rapamycin (U.S. Patent
20 No. 4,650,803).
WO 95/14023
PCT/US94/12777
-4-
Fermentation and purification of rapamcyin and 30-demethoxy
rapamycin have been described in the literature (C. Vezina et al. /. Antibiot.
(Tokyo), 1975, 28 (10), 721; S. N. Sehgal et aL, J. Antibiot. (Tokyo), 1975,
25(10), 727; 1983, 5(5(4), 351; N. L. Pavia et al., J. Natural Products, 1991,
5 54(1), 167-177).
Numerous chemical modifications of rapamycin have been attempted.
These include the preparation of mono- and di-ester derivatives of rapamycin
(WO 92/05179), 27-oximes of rapamycin (EPO 467606); 42-oxo analog of
rapamycin (U.S. Patent No. 5,023,262); bicyclic rapamycins (U.S. Patent No.
10 5,120,725); rapamycin dimers (U.S. Patent No. 5,120,727); silyl ethers of
rapamycin (U.S. Patent No. 5,120,842); and arylsulfonates and sulfamates (U.S.
Patent No. 5,177, 203). Rapamycin was recently synthesized in its naturally
occuring enantiomeric form (K. C. Nicolaou et al., J. Am. Chem. Soc, 1993, 775,
4419-4420; S. L. Schreiber, J. Am. Chem. Soc, 1993, 775, 7906-7907; S. J.
15 Danishefsky, J. Am. Chem. Soc, 1993, 775, 9345-9346.
It has been known that rapamycin, like FK-506, binds to FKBP-12
(Siekierka,'J. J.; Hung, S. H. Y.; Poe, M.; Lin, C. S.; Sigal, N. H. Nature, 1989,
341, 755-757; Harding, M. W.; Galat, A.; Uehling, D. E.; Schreiber, S. L. Nature
1989, 341, 758-760; Dumont, F. J.; Melino, M. R.; Staruch, M. J.; Koprak, S. L.;
20 Fischer, P. A.; Sigal, N. H. J. Immunol. 1990, 144, 1418-1424; Bierer, B. E.;
Schreiber, S. L.; Burakoff, S. J. Eur. J. Immunol. 1991, 21, 439-445; Fretz, H.;
Albers, M. W.; Galat, A.; Standaert, R. F.; Lane, W. S.; Burakoff, S. J.; Bierer,
B. E.; Schreiber, S. L. J. Am. Chem. Soc 1991, 775, 1409-1411). Recently it has
been discovered that the rapamycin/FKBP-12 complex binds to yet another
25 protein, which is distinct from calcineurin, the protein that the FK-506/FKBP-12
complex inhibits (Brown, E. J.; Albers, M. W.; Shin, T. B.; Ichikawa, K.; Keith,
C. T.; Lane, W. S.; Schreiber, S. L. Nature 1994, 369, 756-758.; Sabatini, D. M.;
Erdjument-Bromage, H.; Lui, M.; Tempest, P.; Snyder, S. H. Cell, 1994, 78, 35-
43).
30 Although some of these modified compounds exhibit immunosuppressive
activity, the need remains for macrocyclic immunosuppressants which do not
have the serious side effects frequently associated with immunosuppressant
therapy. Accordingly, one object of this invention is to provide novel
WO 95/14023
PCT/US94/12777
-5-
semisynthetic macrolides which possess the desired immunomodulatory activity
but which may be found to rninimize untoward side effects.
Another object of the present invention is to provide synthetic processes
for the preparation of such compounds from starting materials obtained by
5 fermentation, as well as chemical intermediates useful in such synthetic
processes.
A further object of the invention is to provide pharmaceutical
compositions containing, as an active ingredient, at least one of the above
compounds. Yet another object of the invention is to provide a method of
10 treating a variety of disease states, including post-transplant tissue rejection and
autoimmune disfunction.

(a) A three-neck 2 L roundbottom flask equipped with an overhead stirrer
was charged with diethylether (800 mL), chloroacetyl chloride (40 mL, 0.5 mol)
and (lR)-(-)-nopol (85.3 mL, 0.5 mol). At 0 °C, triethylamine (69.5 mL, 0.5
mol) was added dropwise over 15 minutes. After stirring at 0 °C for 1 hour, the
25 mixture was warmed to ambient temperature and stirred for 18 hours. The
mixture was vacuum filtered through a Buchner funnel and the white cake was
extracted with ether (2 x 200 mL). The filtrates were then washed sequentially
with 0.5 N HC1 (500 mL), water (500 mL) and brine (500 mL). After drying the
organics (Na2SC>4), the mixture was filtered and concentrated to a pale tan oil
30 (104 g). The resultant nopol chloroacetate was sufficiently pure to carry forward
in the next step.

for 5 minutes and cooled to room temperature. Nopol chloroacetate from step (a)
(5.85 g, 24.17 mmol) was added, and the reaction was stirred for 30 minutes.

washed sequentially with saturated sodium bicarbonate (30 mL) and 10% sodium
5 bisulfite (30 mL), dried (sodium sulfate) and concentrated in vacuo to an amber
oil (7 g). The resulting nopol iodoacetate was sufficiently pure to use in the next

In vitro Assay of Biological Activity
The immunosuppressant activity of the compounds of the present
invention was determined using the human mixed lymphocyte reaction (MLR)
5 assay described by Kino, T. et al. in Transplantation Proceedings, XIX(5):36-
39, Suppl. 6 (1987). The in vitro immunosuppressant activity of the compounds
of the present invention was determined in a one way allogeneic mixed leukocyte
response (MLR) assay using rat lymph node and spleen cells, conducted as
follows: Responder cells were obtained from the lymph nodes of Brown Norway
10 rats (Harlan Sprague Dawley, Inc., Indianapolis, IN) and the stimulator cells
were isolated from the spleens of Lewis rats (Harlan Sprague Dawley, Inc.,
Indianapolis, IN). 200-250 gram rats were sacrificed by asphyxiation with CO2
and the popliteal and mesenteric lymph nodes or spleen were removed by sterile
dissection. The tissue was placed in RPMI 1640 supplemented with 10%
15 heat-inactivated fetal bovine serum, 2 mM L-glutamine, 50 (J.M
2-mercaptoethanol, 50 units/mL penicillin G, and 50 ng/mL streptomycin
(complete RPMI medium). After mechanically disrupting the tissue and
allowing debris to settle at 1 x g, the suspended cells were aspirated. The cell
suspensions were centrifuged 10 min at 400 x g and the responder cells
20 resuspended in complete RPMI medium at 2 x 10 6 cells/mL. To remove red
cells, the spleen cells were suspended in 0.14 M NH4CI/O.OI7 M Tris-HCl lysing
buffer, pH 7.4, for 2 minutes, mixed with RPMI 1640, and centrifuged as before.
The spleen cells were subsequently washed three times by centrifugation in
RPMI 1640. To inhibit their abilty to proliferate, spleen cells were suspended at
25 1 x 10 7 cells/mL in complete RPMI medium and incubated in the presence of 25
|J.g/mL of mitomycin C for 30 minutes at 37 °C. The mitomycin C-treated spleen
cells were washed three times by centrifugation in RPMI 1640 before being
suspended in complete RPMI medium at 4 x 10 6 cells/mL.
For the MLR, 1 x 10 5 lymph node cells were mixed with 5 x 10 5
30 mitomycin C-treated spleen cells in 0.2 raL of complete RPMI 1640 and cultured
in 95% air / 5% CO2 atmosphere for 120 hours at 37 °C. Test compounds were
dissolved at 10 mM in dimethylsulfoxide, diluted in complete RPMI medium,
and 25 u\L of the test compound was added to the lymph node cells before
addition of the spleen cells. During the final 6 hours, the cells were labeled with
WO 95/14023
PCTAJS94/12777
-135-
0.5 flCi per well of tritiated thymidine ( 3 H-TdR; DuPont NEN Research
Products, Boston, MA). The cells were harvested by vacuum filtration onto
glass fiber filters and the filter radioactivity measured with a MATRIX 9600
direct beta counter (Packard Instrument Company, Meriden, CT). To calculate
the compound concentration which caused 50% inhibition (IC 50 ) in an assay, the
inhibition data was fit to a log-logistic linear function.
The results of the assay, shown below in Table 1, demonstrate that the
compounds tested are effective immunomodulators at nanomolar concentrations.

5 The compounds of the invention, including but not limited to those
specified in the examples, possess immunomodulatory activity in mammals
(especially humans). As immunosuppressants, the compounds of the present
invention axe useful for the treatment and prevention of immune-mediated
diseases such as the resistance by transplantation of organs or tissue such as
10 heart, kidney, liver, medulla ossium, skin, cornea, lung, pancreas, intestinum
tenue, limb, muscle, nervus, duodenum, small-bowel, pancreatic-islet-cell, etc.;

Hashimoto's thyroiditis, multiple sclerosis, myasthenia gravis, type I diabetes
15 uveitis, allergic encephalomyelitis, glomerulonephritis, and the like; and further
infectious diseases caused by pathogenic microorganisms, such as HIV. In the
particular cases of HIV- 1, HIV-2 and related retroviral strains, inhibition of T-
cell proliferation will suppress the replication of the virus, since the virus relies
upon the T-cell's proliferative functions to replicate. Further uses include the
20 treatment and prophylaxis of inflammatory and hyperproliferative skin diseases
and cutaneous manifestations of immunologically-mediated illnesses, such as
psoriasis, atopical dermatitis, contact dermatitis and further eczematous
dermatitises, seborrhoeis dermatitis, Lichen planus, Pemphigus, bullous

10 and dust asthma), particularly chronic or inveterate asthma (for example, late
asthma and airway hyper-responsiveness), bronchitis and the like; inflammation
of mucosa and blood vessels such as gastric ulcers, vascular damage caused by
ischemic diseases and thrombosis. Moreover, hyperproliferative vascular
diseases such as intimal smooth muscle cell hyperplasia, restenosis and vascular
15 occlusion, particularly following biologically or mechanically mediated vascular
injury could be treated or prevented by the compounds of the invention. Other
treatable conditions include but are not limited to ischemic bowel diseases,
inflammatory bowel diseases, necrotizing enterocolitis, intestinal lesions
associated with thermal burns and leukotriene B4-mediated diseases; intestinal
20 inflammations/allergies such as Coeliac diseases, proctitis, eosinophilic
gastroenteritis, mastocytosis, Crohn's disease and ulcerative colitis; food-related
allergic diseases which have symptomatic manifestation remote from the gastro-
intestinal tract (e.g. migraine, rhinitis and eczema); renal diseases such as
interstitial nephritis, Goodpasture's syndrome, hemolytic-uremic syndrome and
25 diabetic nephropathy; nervous diseases such as multiple myositis, Guillain-Barre
syndrome, Meniere's disease, polyneuritis, multiple neuritis, mononeuritis and
radiculopathy; endocrine diseases such as hyperthyroidism and Basedow's
disease; hematic diseases such as pure red cell aplasia, aplastic anemia,
hypoplastic anemia, idiopathic thrombocytopenic purpura, autoimmune
30 hemolytic anemia, agranulocytosis, pernicious anemia, megaloblastic anemia and
anerythroplasia; bone diseases such as osteoporosis; respiratory diseases such as
sarcoidosis, fibroid lung and idiopathic interstitial pneumonia; skin disease such
as dermatomyositis, leukoderma vulgaris, ichthyosis vulgaris, photoallergic
sensitivity and cutaneous T cell lymphoma; circulatory diseases such as
WO 95/14023
PCT/US94/12777
-138-
arteriosclerosis, atherosclerosis, aortitis syndrome, polyarteritis nodosa and
myocardosis; collagen diseases such as scleroderma, Wegener's granuloma and
Sjogren's syndrome; adiposis; eosinophilic fasciitis; periodontal disease such as
lesions of gingiva, periodontium, alveolar bone and substantia ossea dentis;
5 nephrotic syndrome such as glomerulonephritis; male pattern aleopecia or
alopecia senilis by preventing epilation or providing hair germination and/or
promoting hair generation and hair growth; muscular dystrophy; Pyoderma and
Sezary's syndrome; Addison's disease; active oxygen-mediated diseases, as for
example organ injury such as ischemia-reperfusion injury of organs (such as
10 heart, liver, kidney and digestive tract) which occurs upon preservation,
transplantation or ischemic disease (for example, thrombosis and cardiac
infraction): intestinal diseases such as endotoxin-shock, pseudomembranous
colitis and colitis caused by drug or radiation; renal diseases such as ischemic
acute renal insufficiency and chronic renal insufficiency; pulmonary diseases
15 such as toxinosis caused by lung-oxygen or drug (for example, paracort and

(for example, air pollution), aging, carcinogenis, metastasis of carcinoma and
hypobaropathy; diseases caused by histamine or leukotriene-C4 release; Behcet's
disease such as intestinal-, vasculo- or neuro-Behcet's disease, and also Behcet's
which affects the oral cavity, skin, eye, vulva, articulation, epididymis, lung,
25 kidney and so on. Furthermore, the compounds of the invention are useful for
the treatment and prevention of hepatic disease such as immunogenic diseases
(for example, chronic autoimmune liver diseases such as autoimmune hepatitis,
primary biliary cirrhosis and sclerosing cholangitis), partial liver resection, acute
liver necrosis (e.g. necrosis caused by toxin, viral hepatitis, shock or anoxia), B-
30 virus hepatitis, non-A/non-B hepatitis, cirrhosis (such as alcoholic cirrhosis) and
hepatic failure such as fulminant hepatic failure, late-onset hepatic failure and
"acute-on-chronic" liver failure (acute liver failure on chronic liver diseases), and
moreover are useful for various diseases because of their useful activity such as
WO 95/14023
PCT/US94/12777
-139-
augmention of chemotherapeutic effect, cytomegalovirus infection, particularly
HCMV infection, anti-inflammatory activity, and so on.
Additionally, compounds of the invention possess FK-506 antagonistic
properties. The compounds of the present invention may thus be used in the
5 treatment of immunodepression or a disorder involving immunodepression.
Examples of disorders involving immunodepression include AIDS, cancer, senile
dementia, trauma (including wound healing, surgery and shock) chronic bacterial
infection, and certain central nervous system disorders. The immunodepression *
to be treated may be caused by an overdose of an immunosuppressive
10 macrocyclic compound, for example derivatives of 12-(2-cyclohexyl-l-
methylvinyl)-13, 19,21,27 -tetramethyl- 1 l,28-dioxa-4-azatricyclo[22.3.1.0 4 <9]
octacos-18-ene such as FK-506, or rapamycin. Overdosing of such medicants by
patients is quite common upon their realizing that they have forgotten to take
their medication at the prescribed time and can lead to serious side effects.
15 The ability of the compounds of the invention to treat proliferative
diseases can be demonstrated according to the methods described in Bunchman
ET and CA Brookshire, Transplantation Proceed. 23 967-968 (1991); Yamagishi,
et al., Biochem. Biophys. Res. Comm. 191 840-846 (1993); and Shichiri, et al., J.
Clin. Invest. 87 1867-1871 (1991). Proliferative diseases include smooth muscle
20 proliferation, systemic sclerosis, cirrhosis of the liver, adult respiratory distress
syndrome, idiopathic cardiomyopathy, lupus erythematosus, diabetic retinopathy
or other retinopathies, psoriasis, scleroderma, prostatic hyperplasia, cardiac
hyperplasia, restenosis following arterial injury or other pathologic stenosis of
blood vessels.
25 Aqueous liquid compositions of the present invention are particularly
useful for the treatment and prevention of various diseases of the eye such as
autoimmune diseases (including, for example, conical cornea, keratitis, dysophia
epithelialis comeae, leukoma, Mooren's ulcer, sclevitis and Graves'
ophthalmopathy) and rejection of corneal transplantation.

When used in the above or other treatments, a therapeutically effective
amount of one of the compounds of the present invention may be employed in
pure form or, where such forms exist, in pharmaceutically acceptable salt, ester
or prodrug form. Alternatively, the compound may be administered as a
WO 95/14023
PCTYUS94/12777
-140-
pharmaceutical composition containing the compound of interest in combination
with one or more pharmaceutically acceptable excipients. The phrase
"therapeutically effective amount" of the compound of the invention means a
sufficient amount of the compound to treat disorders, at a reasonable benefit/risk
5 ratio applicable to any medical treatment. It will be understood, however, that
the total daily usage of the compounds and compositions of the present invention
will be decided by the attending physician within the scope of sound medical
judgement. The specific therapeutically effective dose level for any particular
patient will depend upon a variety of factors including the disorder being treated
10 and the severity of the disorder; activity of the specific compound employed; the
specific composition employed; the age, body weight, general health, sex and
diet of the patient; the time of administration, route of administration, and rate of
excretion of the specific compound employed; the duration of the treatment;
drugs used in combination or coincidental with the specific compound employed;
15 and like factors well known in the medical arts. For example, it is well within
the skill of the art to start doses of the compound at levels lower than required to
achieve the desired therapeutic effect and to gradually increase the dosage until
the desired effect is achieved.
The total daily dose of the compounds of this invention administered to a
20 human or lower animal may range from about 0.001 to about 3 mg/kg/day. For
purposes of oral administration, more preferable doses may be in the range of
from about 0.005 to about 1.5 mg/kg/day. If desired, the effective daily dose
may be divided into multiple doses for purposes of administration; consequently,
single dose compositions may contain such amounts or submultiples thereof to
25 make up the daily dose.
The pharmaceutical compositions of the present invention comprise a
compound of the invention and a pharmaceutically acceptable carrier or
excipient, which may be administered orally, rectally, parenterally,
intracisternally, intravaginally, intraperitoneally, topically (as by powders,
30 ointments, drops or transdermal patch), bucally, or as an oral or nasal spray.
The phrase "pharmaceutically acceptable carrier" means a non-toxic solid, semi-
solid or liquid filler, diluent, encapsulating material or formulation auxiliary of
any type. The term "parenteral" as used herein refers to modes of administration
WO 95/14023
PCTVUS94/12777
-141-
which include intravenous, intramuscular, intraperitoneal, intrasternal,
subcutaneous and intraarticular injection and infusion.
Pharmaceutical compositions of this invention for parenteral injection
comprise pharmaceutically acceptable sterile aqueous or nonaqueous solutions,
5 dispersions, suspensions or emulsions as well as sterile powders for
reconstitution into sterile injectable solutions or dispersions just prior to use.
Examples of suitable aqueous and nonaqueous carriers, diluents, solvents or
vehicles include water, ethanol, polyols (such as glycerol, propylene glycol,
polyethylene glycol, and the like), carboxymethylcellulose and suitable mixtures
10 thereof, vegetable oils (such as olive oil), and injectable organic esters such as
ethyl oleate. Proper fluidity can be maintained, for example, by the use of
coating materials such as lecithin, by the maintenance of the required particle
size in the case of dispersions, and by the use of surfactants.
These compositions may also contain adjuvants such as preservatives,
15 wetting agents, emulsifying agents, and dispersing agents. Prevention of the
action of microorganisms may be ensured by the inclusion of various
antibacterial and antifungal agents, for example, paraben, chlorobutanol, phenol
sorbic acid, and the like. It may also be desirable to include isotonic agents such
as sugars, sodium chloride, and the like, Prolonged absorption of the injectable
20 pharmaceutical form may be brought about by the inclusion of agents which
delay absorption such as aluminum monostearate and gelatin.
In some cases, in order to prolong the effect of the drug, it is desirable to
slow the absorption of the drug from subcutaneous or intramuscular injection.
This may be accomplished by the use of a liquid suspension of crystalline or
25 amorphous material with poor water solubility. The rate of absorption of the
drug then depends upon its rate of dissolution which, in turn, may depend upon
crystal size and crystalline form. Alternatively, delayed absorption of a
parenterally administered drug form is accomplished by dissolving or suspending
the drug in an oil vehicle.
30 Injectable depot forms are made by forming microencapsule matrices of
the drug in biodegradable polymers such as polylactide-polyglycolide.
Depending upon the ratio of drug to polymer and the nature of the particular
polymer employed, the rate of drug release can be controlled. Examples of other
biodegradable polymers include poly(orthoesters) and poly(anhydrides) Depot
WO 95/14023
PCT/US94/12777
-142-
injectable formulations are also prepared by entrapping the drug in liposomes or
microemulsions which are compatible with body tissues.
The injectable formulations can be sterilized, for example, by filtration
through a bacterial-retaining filter, or by incorporating sterilizing agents in the
5 form of sterile solid compositions which can be dissolved or dispersed in sterile
water or other sterile injectable medium just prior to use.
Solid dosage forms for oral administration include capsules, tablets, pills,
powders, and granules. In such solid dosage forms, the active compound is
mixed with at least one inert, pharmaceutically acceptable excipient or carrier
10 such as sodium citrate or dicalcium phosphate and/or a) fillers or extenders such
as starches, lactose, sucrose, glucose, mannitol, and silicic acid, b) binders such
as, for example, carboxymethylcellulose, alginates, gelatin,
polyvinylpyrrolidone, sucrose, and acacia, c) humectants such as glycerol, d)
disintegrating agents such as agar-agar, calcium carbonate, potato or tapioca
15 starch, alginic acid, certain silicates, and sodium carbonate, e) solution retarding
agents such as paraffin, f) absorption accelerators such as quaternary ammonium
compounds, g) wetting agents such as, for example, cetyl alcohol and glycerol
monostearate, h) absorbents such as kaolin and bentonite clay, and i) lubricants
such as talc, calcium stearate, magnesium stearate, solid polyethylene glycols,
20 sodium lauryl sulfate, and mixtures thereof. In the case of capsules, tablets and
pills, the dosage form may also comprise buffering agents.
Solid compositions of a similar type may also be employed as fillers in
soft and hard-filled gelatin capsules using such excipients as lactose or milk
sugar as well as high molecular weight polyethylene glycols and the like.
25 The solid dosage forms of tablets, dragees, capsules, pills, and granules
can be prepared with coatings and shells such as enteric coatings and other
coatings well known in the pharmaceutical formulating art. They may optionally
contain opacifying agents and can also be of a composition that they release the
active ingredient(s) only, or preferentially, in a certain part of the intestinal tract,
30 optionally, in a delayed manner. Examples of embedding compositions which
can be used include polymeric substances and waxes.
The active compounds can also be in micro-encapsulated form, if
appropriate, with one or more of the above-mentioned excipients.
WO 95/14023
PCT/US94/12777
-143-
Liquid dosage forms for oral administration include pharmaceutically
acceptable emulsions, solutions, suspensions, syrups and elixirs. In addition to
the active compounds, the liquid dosage forms may contain inert diluents
commonly used in the art such as, for example, water or other solvents,
5 solubilizing agents and emulsifiers such as ethyl alcohol, isopropyl alcohol, ethyl
carbonate, ethyl acetate, benzyl alcohol, benzyl benzoate, propylene glycol, 1,3-
butylene glycol, dimethyl formamide, oils (in particular, cottonseed, groundnut,
corn, germ, olive, castor, and sesame oils), glycerol, tetrahyarofurfuryl alcohol,
polyethylene glycols and fatty acid esters of sorbitan, and mixtures thereof.
10 Besides inert diluents, the oral compositions can also include adjuvants
such as wetting agents, emulsifying and suspending agents, sweetening,
flavoring, and perfuming agents.
Suspensions, in addition to the active compounds, may contain
suspending agents as, for example, ethoxylated isostearyl alcohols,
15 polyoxyethylene sorbitol and sorbitan esters, microcrystalline cellulose,
aluminum metahydroxide, bentonite, agar-agar, and tragacanth, and mixtures
thereof.
Topical administration includes administration to the skin or mucosa,
including surfaces of the lung and eye. Compositions for topical administration,
20 including those for inhalation, may be prepared as a dry powder which may be
pressurized or non-pressurized. In non-pressurized powder compositions, the
active ingredient in finely divided form may be used in admixture with a larger-
sized pharmaceutically acceptable inert carrier comprising particles having a
size, for example, of up to 100 micrometers in diameter. Suitable inert carriers
25 include sugars such as lactose. Desirably, at least 95% by weight of the particles
of the active ingredient have an effective particle size in the range of 0.01 to 10
micrometers.
Alternatively, the composition may be pressurized and contain a
compressed gas, such as nitrogen or a liquified gas propellant. The liquified
30 propellant medium and indeed the total composition is preferably such that the
active ingredient does not dissolve therein to any substantial extent. The
pressurized composition may also contain a surface active agent. ■ The surface
active agent may be a liquid or solid non-ionic surface active agent or may be a
WO 95/14023
PCT/US94/12777
-144-
solid anionic surface active agent. It is preferred to use the solid anionic surface
active agent in the form of a sodium salt.
A further form of topical administration is to the eye, as for the treatment
of immune-mediated conditions of the eye such as automimmue diseases,
5 allergic or inflammatory conditions, and corneal transplants. The compound of
the invention is delivered in a pharmaceutically acceptable ophthalmic vehicle,
such that the compound is maintained in contact with the ocular surface for a
sufficient time period to allow the compound to penetrate the corneal and
internal regions of the eye, as for example the anterior chamber, posterior
10 chamber, vitreous body, aqueous humor, vitreous humor, cornea, iris/cilary, lens,
choroid/retina and sclera. The pharmaceutically acceptable ophthalmic vehicle
may, for example, be an ointment, vegetable oil or an encapsulating material.
Compositions for rectal or vaginal administration are preferably
suppositories which can be prepared by mixing the compounds of this invention
15 with suitable non-irritating excipients or carriers such as cocoa butter,
polyethylene glycol or a suppository wax which are solid at room temperature
but liquid at body temperature and therefore melt in the rectum or vaginal cavity
and release the active compound.
Compounds of the present invention can also be administered in the form
20 of liposomes. As is known in the art, liposomes are generally derived from
phospholipids or other lipid substances. Liposomes are formed by mono- or
multi-lamellar hydrated liquid crystals that are dispersed in an aqueous medium.
Any non-toxic, physiologically acceptable and metabolizable lipid capable of

INTERNATIONAL SEARCH REPORT
Intern^onai application No.
PCT/US 94/ 12777
Box I Observations where certain claims were found unsearchable (Continuation of item I of first sheet)
This international search report has not been established in respect of certain claims under Article 17(2)(a) for the following reasons:
1. Claims Nos.:
because they relate to subject matter not required to be searched by this Authority, namely:
Although claims 38-48 are directed to a method of treatment of the human/
animal body (Rule 39.1.(iv), the search has been carried out and based on
the alleged effects of the compounds.
2 ' ^ beaSsVthey relate to parts of the international application that do not comply with the prescribed requirements to such
an extent that no meaningful international search can be carried out, specifically:
be^se'they are dependent claims and are not drafted in accordance with the second and third sentences of Rule 6.4(a).
Box II Observations where unity of invention is lacking (Continuation of item 2 of first sheet)
This International Searching Authority found multiple inventions in this international application, as follows:
1 . Q^j As all required additional search fees were timely paid by the applicant, this international search report covers all
searchable claims.
2. [""I As all searchable claims could be searches without effort justifying an additional fee, this Authority did not invite payment
of any additional fee.
3. A.s only some of the required additional search fees were timely paid by the applicant,
' 1 covers only those claims for which fees were paid, specifically claims Nos.:
this international search report
4 I I No required additional search fees were timely paid by the applicant. Consequently, this international search report is
1 1 restricted to the invention first mentioned in the claims; it is covered by claims Nos.:
Remark on Protest [^] The additional search fees were accompanied by the applicant's protest.
| | No protest accompanied the payment of additional search fees.
